ever since i got a new Base Idle Screw from Mach V, my oil light comes on when im idleing in drive, but when im in park its idleing perfect. when im driving nothings wrong w/ the oil pressure. i also tried to raise my idle but when i do that i get an idle surge when its in park. my oil level is fine, but i dont know whats happening when im idleing in drive, PLEASE give me some ideas.
